Life cycle thinking refers to the consideration of environmental impacts throughout the various stages of a product's existence and the endeavor to minimize these impacts whenever feasible. It aims to prevent the transfer of environmental burdens from one stage to another. Additionally, life cycle thinking acknowledges the role of technological advancement in addressing environmental concerns.
This approach is adopted by companies in the development of eco-friendly products, by consumers in making conscious product selections, and by governments in establishing regulatory standards to mitigate environmental effects. It involves identifying key areas for reduction while also promoting consumer awareness.
There are many different approaches to life cycle thinking that all involve looking at life cycle-generated impacts and ways to minimize these impacts. An important component is the avoidance of burden shifting, which ensures that improvements in one stage are not achieved at the expense of another stage. Impact measurement focuses on decreasing environmental impact and resource use throughout all stages of a process.
Life-cycle assessment (LCA or life cycle analysis) is a technique used to assess potential environmental impacts of a product at different stages of its life. This technique takes a "cradle-to-grave" or a "cradle-to-cradle" approach and looks at environmental impacts that occur throughout the lifetime of a product from raw material extraction, manufacturing and processing, distribution, use, repair and maintenance, disposal, and recycling.
Life cycle management is a business approach to managing the total life cycle of products and services. It follows the life cycle thinking that businesses, through the activities they must perform, have environmental, social, and economic impacts. LCM is used to understand and analyze the life cycle stages of products and services of a business, identify potential economic, social, or environmental risks and opportunities at each stage and create ways to act upon those opportunities and reduce potential risks.

Industrial ecology (IE) is the study of material and energy flows through industrial systems. The global industrial economy can be modelled as a network of industrial processes that extract resources from the Earth and transform those resources into products and services which can be bought and sold to meet the needs of humanity. Industrial ecology seeks to quantify the material flows and document the industrial processes that make modern society function.
The first part of the course (~20%) is devoted to green chemistry and life cycle assessment.The remainder focuses on process intensification (fundamentals, detailed description of a few selected te
This course introduces tools to design and evaluate sustainable routes for chemicals and materials manufacture. You will understand approaches to process design and optimization, from the molecular to
The class introduces the concept of circular economy and its applications to building design, with a focus on design with reused components, design for disassembly, and life-cycle assessment. The clas
Changing consumption patterns and global population growth lead to ever-increasing waste generation. Human activity and waste generation are irrevocably linked, and the current situation thus calls for a more circular approach to waste management, where wa ...
The net-zero emission target necessitates a significantly expanded deployment of clean technologies compared to their current utilization. Precisely estimating the future potential of these technologies requires a thorough understanding of their cost and c ...
The building industry is responsible for 35% of all solid waste in Europe and more than a third of greenhouse gas (GHG) emissions. To address this, applying circular economy principles to the building sector is crucial, for example by reusing building elem ...
